Nosequien y Los Nosecuantos, a Peruvian pop rock experimental band fronted by singer, comedian, and TV host Raúl Romero, emerged in 1988. The group quickly gained attention for their eclectic blend of genres, including rap, reggae, Peruvian waltz, and ska, along with satirical elements that set them apart. Their debut album Con el Respeto Que Se Merecen was released on January 2, 1991. The band continued to evolve musically, releasing albums such as Walter in July 1995, Amorfo in November 2000, and Pisco Sour in March 2013. The band's unique theatrical performances, led by Romero’s comedic skills, made their concerts a distinctive experience.
